Strong, smooth, and reliable☕️
Flavor Name: Major Dickason's Blend, Size: 10.5 Ounce (Pack of 1)
This is iur go-to dark roast. It’s bold without tasting burnt, and the flavor is really smooth. Wakes you up without any weird aftertaste. I’ve had it a bunch of times and it’s always consistent. Solid cup of coffee.

Flavor Name: Major Dickason's Blend, Size: 18 Ounce (Pack of 1)
Always shopped locally for Major Dickason's, looking for sales. Amazon price is good and the exp. date is much farther out than anything on the local shelves.
